Video Transcript

So we're facing these problems of climate change and greenhouse gas emissions and oil security and sustainable energy for growing transportation systems around the world. What are we going to do about it? Some of the things we know will work because they've worked in the past. For example, fuel economy standards; we know those work. And we know that we have the technology to increase fuel economy by 50% over the next 10 or 12 years, and maybe with technological advances, 100% over a 20-year period. But we may have to give up increasing the horsepower and increasing—continuing to increase the horsepower, continuing to increase the size of the vehicle. So the price of dealing with climate change, dealing with our oil security problem, may be giving up the horsepower race in vehicles and giving up the size race in vehicles.
